中文版

新特性
  • 连接活动指示灯: 连接组新增可交互的 TX/RX 与控制线指示灯，实时闪烁反映收发与控制线状态；退役旧版控制线界面，改用指示灯呈现
  • 串口控制线: 新增串口控制线处理，设置对话框新增 Control Lines 标签页
  • Modbus 请求构建器: 工具菜单新增 Modbus 请求构建器
  • 逐项快捷设置: 所有分组均支持逐项快捷设置，快捷设置选择器移入设置对话框
  • 行结束符下拉框: 以 Line Ending 下拉框替代发送区的自动换行复选框
  • 恢复上次连接: 启动时自动恢复上次退出时打开的连接
  • 终端光标与真实发送统计: 终端模式新增光标显示，发送计数改为真实统计
界面改进
  • TCP/UDP 模式界面: 静默服务器错误弹窗，优化 TCP/UDP 模式界面
  • 工具栏: 重做日志记录与快捷设置的工具栏控件
  • 多处 UI 对齐与打磨: 统一接收 Auto FL 与发送 Loop 行、对齐 Line Ending 与 Append Checksum 下拉框等
修复与完善
  • 设置默认值: 补齐并保护设置面板中 Log/Display 相关默认值，不再保存空的 Rx/Tx 时间格式
  • .spu 会话加载: 以 toBool 解析 .spu 布尔标记，确保已保存的 true 值在重载后保留
  • 国际化: 中文界面将格式单选项标注为 Text 而非 ASCII
  • 日志目录: 打开日志文件前先创建日志目录

English

Features
  • Connection activity lamps: The connection group gains interactive TX/RX and control-line indicator lamps that blink to reflect live traffic and control-line state; the classic control-line UI is retired in favour of the lamps
  • Serial control lines: Added serial control line handling with a new Control Lines tab in the settings dialog
  • Modbus request builder: Added a Modbus request builder to the Tools menu
  • Per-field quick settings: Quick settings are now available per field across all groups, with the picker moved into the settings dialog
  • Line Ending combo: Replaced the send auto-feed checkbox with a Line Ending combo
  • Restore last connection: Automatically restores the connection that was open at last exit
  • Terminal caret & honest Tx metrics: The terminal mode shows a caret and reports real Tx counts
UI Improvements
  • TCP/UDP mode UI: Silenced the server-error popup and polished the TCP/UDP mode UI
  • Toolbar: Reworked the log-recording and quick-settings toolbar controls
  • UI alignment & polish: Unified the receive Auto FL and send Loop rows, aligned the Line Ending and Append Checksum combos, and more
Fixes & Enhancements
  • Settings defaults: Seeded and guarded the remaining Log/Display defaults in the settings panel; never store empty Rx/Tx time formats
  • .spu session loading: Parse .spu bool flags with toBool so saved true values survive reload
  • Internationalization: Label the format radios Text, not ASCII, in Chinese
  • Log directory: Create the log directory before opening the log file
